  • Each diamond is different, with many types of inclusions. Their type, occurrence, location and visibility within the diamond are several variables that are evaluated in the grading process. These not only help to determine the value of the diamond, but also to recognize and identify the stone.

    Clarity evaluation will be based on the following five elements: the number, type, size, location and visibility of inclusions. The most common inclusions are: pinpoint, needle, crystal, feather, specific and dispersed cloud and twinning wisp. We grade three pinpoints closed together always as a cloud.
